IMPROVEMENT IN PLANES FOR CUTTING BLIND-SLATS.

TO ALL WHOM IT MAY CONCERN:

Be it known that we, JAMES L..BESS and Anni I'IAGNY, oi Keokuk, in the county of Lee, nnd'State of Iowa, have invented a new and useful Improvement in Planes for Cutting Blind-Slots; and we do hereby declare thefollo-wing to be a full, clear, and exact description of the nature. coustru ction, and operation of the same, reference beinghad to the accompanying drawings, which are made a part of this specification, and in which- Figure 1 is a perspective view of our improved plane, showing the some in its operating position.

Figure is an under side perspective view of the same.

similar letters of reference indicate correspondingparts in the two. figures.

The subject of our invention is a. hand-plane adapted to out two or more thinslatsfor window-shades, blinds, &c., at every stroke or movement, and at the same time dress or prepare the material for the operation.

The following description will enable others skilled in 'the art to which my invention appertains to fully understand and use the same: i

A A represent the body of the plane, which is formed with a guide-way or gauge groove, 13, which embraces the'edge of the plank from which the slats are cut when the .plane is in operation. The'material or plank is clamped immovably, and the plane is driven over itsedge by means of the handle A, in the same manner as an ordinary smoothing-plane. O is a bit or cutter extending across the gauge-groove B',1ind this cutter, when the .plane is inoperation, cuts from the material ortplank a stripoi'suflicient thickness to form the slats. A suitable throat,-c, is formed between the bottom of the plane and the cutter O to make room for the slats as they arecut' from the stuff. The sides of the plank are dressed by the knives .D D, situated at either side of the groove 13, and secured in position by keys D D. Before reaching the cutter C that portion of the wood which is removed by each stroke of the plane is divided longitudinally by the pointed, perpendicular knives E E E, and by this means twmslats are produced by every eitective movement of the plane. The outer knives E E are secured in position and made adjustable by the screws F F, which enter the plane from opposite directions, as shown in fig. 1, but for convenience, the central knife E is held and made adjustable by means of the key F. The two parts of the plane A A are held'together by means of the screws G G, which-enable said parts to be adjusted from or toward'each other, and thus vary the width of the gauge-groove according to' the thickness of the material, or in order to vary the width of the slats. The cutter 0 passes through slots in the sides of the plane, and is retained iniproper working position by the jaws H 'H, 'vi'hich-are slotted and held tovthe opposite sidescfthe plane by the screws hi By means of these jaws the knife 0 may be adjusted so as to cut slats of any desired thickness. The slotted end of the bit or cutter O is held to the jaw H by the screw it, which admits of the lateral adjustment of the jaw upon the bit when the plane is increased or diminished in width by the screws G G. i

Having thus-described my invention, the followin'g i's whatwe claim as new herein, and desire to secure by Letters Patent: I V i The arrangement of the slitting cutters E-E E, edge-cutters D D, and riving-cutter G in a frame A A, expansible by means of set-scre'wsG G, all as herein described and for the purpose specified.
